The ANTLR4CPP runtimeThis is where the hard part comes. Mvn clean install.As we will see later, we never actually have to invoke this command by hand. Add the antlr4-runtime dependency as shown below. The mac-build script should set you up with all requirements, and will tell you how to configure CVC4 when it completes successfully.ANTLR (ANother Tool for Language Recognition) is a tool to define such grammar. Then, simply run the script contrib/mac-build, which installs a few ports from the MacPorts repository, then compiles and installs antlr3c using the get-antlr-3.4 script (as described next).Cmake extension included with the runtime, makes it possible to add ANTLR 4 as a dependency with minimal changes to the project.Let’s take a moment to explore the contents of this magnificent file: That, combined with a handy file with the. Basic: ExternalProject with remoteFor those unaware, ExternalProject is a neat package from CMake that makes easy to include… well… projects from outside your project. You can get it in Debian-based distros via $ sudo apt-get install uuid-dev Compilation exampleBeware: The compilation of the library takes a long time. They are not the only ones and they both rely on the ExternalProject CMake package, but after testing several other ways these ones were the easiest to me.NOTE: Under Linux, the runtime needs package uuid-dev. Luckily, the C++ runtime also is built using CMake, which makes the integration at least 20% less painful.The next sections illustrate the two easiest ways I found to integrate it into a project.# INSTALL_COMMAND "" )And that’s it! Simple enough right? We didn’t even have to touch CMakeLists.txt! Just for funzies: Travis-CI integrationIf your project uses Travis as a CI service, you might want to know how these changes affect to your. You can get example grammars from here.# CMakeLists.txt # add generated grammar to demo binary target add_executable (test_antlr main.cpp $ pull #. Create a folder with the following structure, leaving main.cpp and CMakeLists.txt empty. A handy macro that takes care of generating the Lexer and Parser classes and adding a compilation target antlr4cpp_generation_ and the handy variable antlr4cpp_include_dirs_ to include in your CMakeLists.txt.With all this in hand, let’s create a simple project that links against the library: It also sets the useful variables ANTLR4CPP_INCLUDE_DIR (to include in your project’s CMakeLists.txt) and ANTLR4CPP_LIBS, the directory where the compiled libraries will be stored. The ExternalProject_Add call to add antlr4cpp as an external dependency, by downloading it from GitHub and adding a compilation target.
